This Petrogenium course is aimed at Geophysicists, geologists, petrophysicists and reservoir engineers involved in exploration, appraisal and development of clastic oil and gas accumulations. Participants should have a basic knowledge of clastic reservoir geology.

The clastic depositional environment is particularly complex and many factors may cause a
lower than expected recovery. This course aims at:​

  • understanding of the depositional parameters defining the reservoir architecture,​
  • the use of tools to predict subsurface reservoir architecture and​
  • the impact of the heterogeneities on reservoir performance at different scales

Day 1

Framework for reservoir modelling

  • Framework for reservoir modelling
  • Depositional processes and deposits.
  • Geological features influencing hydrocarbon recovery.

Day 2

Clastic Reservoir Architecture and Geologic controls on porosity and permeability.

  • Clastic Reservoir Architecture, determination from seismic, logs, tests and core data
  • Faults, fractures and the influence on fluid flow.
  • Fractured Reservoir.
  • Sealing capacity of faults;
  • Effect of shale baffles on fluid flow.

Day 3

Core acquisition, analysis and interpretation.

  • Core and Log acquisition, analysis and interpretation.
  • Assessing Facies and Rock types using Core data, extrapolation to non – cored wells
  • Geologic controls on porosity and permeability;
  • Estimating, measuring and predicting realistic values for cored and non – cored wells.

Day 4

Core acquisition, analysis and interpretation.

  • Computer modelling of reservoirs
  • Converting Geological models to engineering models.
  • Principles of up scaling (averaging) of Geological data and the application of Geostatistics.

Day 5

Capturing subsurface uncertainties in volume estimates.

  • Capturing subsurface uncertainties in volume estimates.
  • Economic Analysis.
  • FDP planning and integration of fundamental building blocks (well configuration, positioning, spacing)
